Abstract
The Eureka Unit Restoration and Interim Management Plan documents both interim and phase 2 enhancement plans for dune habitat managed by the Nature Conservancy. The Eureka Dune Habitat Mitigation Bank (also known as the Menzies’ Wallflower Mitigation Bank) was established as a condition of approval for the rezoning of 130 acres of Public Recreation lands to Coastal-Dependent Industrial land during the 1983 updates to the "Humboldt County Area Plan" (the County's Local Coastal Program at the time). These 80 acres were set aside as mitigation for the destruction of dune habitat on the newly rezoned parcels. The Eureka Unit and surrounding area contain a mosaic of vegetation types ranging from relatively undisturbed dune vegetation to highly degraded dunes colonized by exotic species, including the largest population on the North Spit of the federally listed Menzies’ wallflower and abundant populations of the endangered beach layia. This plan was scheduled for implementation over a period of five years, the minimum amount of time necessary to carry out the work in two phases to avoid large-scale destabilization of dunes. This second phase of enhancement, as envisioned by the State Coastal Conservancy, was to provide specific methods and costs for restoration of the unit. Since the second phase of enhancement may not be immediately implemented, an interim management plan was prepared.
